CVE-2025-26887 identifies a stored cross-site scripting (XSS) vulnerability in the Eli EZ SQL Reports Shortcode Widget and DB Backup plugin, affecting all versions up to and including 5.21.35. The root cause is improper neutralization of user-supplied input during web page generation, which allows malicious scripts to be injected and stored within the plugin's data. When a victim accesses the affected page or report, the malicious script executes in their browser context, potentially leading to session hijacking, theft of sensitive information, or unauthorized actions performed with the victim's privileges. Stored XSS is particularly dangerous because the payload persists on the server and can affect multiple users without requiring repeated injection. The vulnerability does not require authentication, increasing the attack surface, and no user interaction beyond visiting the affected page is necessary for exploitation. Although no public exploits have been reported yet, the widespread use of WordPress and its plugins makes this a significant concern. The lack of a CVSS score indicates that the vulnerability is newly disclosed, but the technical details and nature of stored XSS justify a high severity rating. The vulnerability affects organizations that use the Eli EZ SQL Reports plugin for database reporting and backup tasks, which are common in web applications relying on WordPress for content management and data reporting.

The impact of CVE-2025-26887 is substantial for organizations using the affected plugin. Successful exploitation can lead to the execution of arbitrary JavaScript in the context of authenticated users, enabling attackers to hijack user sessions, steal cookies, credentials, or other sensitive data, and perform unauthorized actions such as changing settings or injecting further malicious content. This can compromise the confidentiality and integrity of organizational data and user information. Additionally, stored XSS vulnerabilities can facilitate the spread of malware or phishing attacks by injecting malicious scripts into trusted websites. For organizations relying on the plugin for database reporting and backup, the risk extends to potential data exposure or manipulation. The ease of exploitation without authentication and the persistence of the injected payload increase the likelihood of widespread impact. This can damage organizational reputation, lead to regulatory non-compliance, and cause operational disruptions.

1. Monitor for and apply any official patches or updates released by Eli for the EZ SQL Reports Shortcode Widget and DB Backup plugin as soon as they become available. 2. In the absence of a patch, implement a Web Application Firewall (WAF) with rules specifically designed to detect and block XSS payloads targeting the plugin's input fields. 3. Restrict user input to trusted users only and sanitize or validate inputs rigorously before processing or storing them. 4. Conduct regular security audits and code reviews of the plugin's integration points to identify and remediate unsafe input handling. 5. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser. 6. Educate users and administrators about the risks of XSS and encourage cautious interaction with reports or pages generated by the plugin. 7. Consider temporarily disabling the plugin or its vulnerable features if immediate patching is not possible and the risk is deemed high. 8. Monitor logs and user activity for signs of suspicious behavior that may indicate exploitation attempts.
